While I was reinstalling my k-member, I went to bolt back on the lower control arm to the brake spindle and the bolt turns with it. Anyone know how to fix this? Thanks!

 

It is a tapered bolt, just put a socket over the stud (so it is laying on the spindle and tap it(GENTLY!!!). You want to tap the spindle onto the stud in the balljoint and then tighten it up. If you beat on it too hard, you will damage it. Also, if it is turning that easily, make sure it is not worn excessively, it may be time for new ones....

Good luck!
